<span>120
You have 6 tickets, so they can be arranged 6! ways (1*2*3*4*5*6 = 720). From an arrangement, you select the 1st 3 tickets. However, after you've picked the 1st 3 tickets, you have 3 tickets left that you really don't care about their order. So you divide the 720 possible arrangements by 3! which is 6. So the number of possible ways you can select the 3 winners is 6!/3! = 720/6 = 120</span>
Answer:
the sum of triangle is 180°
(2x-15)+(x-5)+42°=180°
2x+x-15°-5°+42°=180°
3x+22°=180°
3x=180°-22
3x=158°
x=52.67°
